Thank you! I was really surprised when I sound this unusual configuration of lifts, so I had to document them. The group really combines a lot of specialties with the different numbers of floors and the motor located on the side of the shaft.

Danke! Trapo Küng ist hauptsächlich auch nur im Raum Basel vertreten.

Yes, this was filmed a few months ago.

Thx!

These lifts consist mostly of Schindler components, more info is in the video description.

Das nennt sich einfahren mit öffnenden Türen und ist bei einigen Aufzügen eine normale Funktion um Zeit zu sparen.

Vorzeitige Tür Öffnung. Ist eine Option.

Wie bereits erwähnt wurde, muss das so. Das ist eine Funktion, die die meisten gängigen Steuerungen bieten, um Zeit zu sparen, was die Transportleistung der Anlage erhöht. Dazu ist auch eine spezielle Schaltung notwendig, die diese kurze Weiterfahrt des Aufzugs auch mit offener Tür unter Gewährleistung der Sicherheit ermöglicht, denn ansonsten kann ein Aufzug nie mit offener Tür fahren.

It is Schindler QKS 9 doors. These lifts consist mostly of Schindler components, more info is in the video description.

Miconic MX-GC mit Variodyn Umrichter. Gibt auch ein komplettes Video von den Anlagen, das ist im Video verlinkt.

I read one of the other comments, is the otis floor selector unreliable?

At 0.8 m/s and 8floors isn't it kida slow?

As can be told by the floor numbering, this lift is in a tall (residential) tower block. SS is the basement, P is parking and R is ground. Then the lift only stops at 4, 8, 12 and so on.

@TheLiftDragon Thanks!

Absolutely, love these selectors as well.

Genau.

They're really nice to watch though. I am most familiar with the Schindler selectors as they're just what's most common around here. As for preference I would go for the Schlieren motorised selectors but these are basically extinct now, sadly. Many companies around here already went for digital selector systems in the 70s, no more complex moving electromechanics.

Indeed, the Schindler drive system called Transitronic has become ultra rare.Things in the US are a bit different but in the rest of the World Mic V was available with 3 drive options, these being Dynatron MV (thyristor with eddy current brake for geared machines), Transitronic M (DC Ward-Leonhard) and Transitronic T (DC with static inverter). Since the Mic V was a controller from the 80s and 90s most installs, especially the faster and bigger ones using Transitronic, have been replaced or modernised by now. The ones in the video here are among the very last of their kind. This also applies to the Schindler Swiss made machines as they seem to be completely different from the DC gearless machines Schindler installed in the US.

@@TheLiftDragon I found an old video of a Transitronic drive installed with a relay controller. Is that just an earlier version of the Transitronic M? ua-cam.com/video/1LHWfQaS5no/v-deo.htmlsi=AqgSZ1bqwigAVxZr

​@@UncommonElevators Ah yes, this is some beautiful old footage! I know these lifts too, though I've never seen them in their original condition. Only after modernisation and now they run on Schindler Port with TX-GC controllers. The system you see there is the 1st generation Transitronic, which came in the flavours of Transitronic D (direct traction = gearless) and Transitronic G (geared). Sadly I don't have any in-depth information on this version of Transitronic. After Transi D/G came the Transitronic 2, which is the drive system you can see in mrmattandmrchay's video of five ways tower. The Transitronic M which is found here is the 3rd and last generation of Transitronic drives with rotary inverters. It was also the last WL type drive produced by Schindler. The first one I know of was the Dynator (not to be confused with Dynatron, which is geared AC with eddy current brake), which used 3 generators to produce main DC voltage, field voltage and auxiliary voltage. The Transitronic drive used other means of generating the extra voltages (valves, thyristors, transformers + rectification) and only needed one generator. I wrote together some history of the different types of Schindler DC drive systems and how to tell them apart: From some point onwards the Schindler drive systems always consisted of some PCBs combined into an "electronics device" (Elektronikgerät) for closed loop control. They were integrated in the drive cabinet, which mostly contained relays and contactors. Back in the days of Aconic transistor controllers, there were the Transitronic 2 and Dynatron 2 options. Transi 2 is the one that uses the EGWL 13 (Elektronikgerät Ward-Leonhard) electronics device with 13 slot-in PCBs. Dynatron 2 had one with 4 PCBs called EGD 4 (Elektronikgerät Dynatron). Production of Dyn 2 lived on into the Age of Miconic B controllers and was still installed in the 80s in combination with them until the thyristor drive Dyn S came around in ~1990. But back to DC. The Transi 2 was the first DC WL drive by Schindler that was able to level intelligently. This had to be set up in a complicated process adjusting resistors. Of the 13 PCBs more than half of them were only for the analogue closed-loop control circuitry to intelligently level the lift. When the digital age cam around in the 80s, the Transitronic M was introduced. Together with the Miconic V controller, the generation of the set-point was now fully digital. The electronics device needed here was now the EGWL 6, which only needed 6 PCBs. The whole process of generating the set-point values was now concentrated on a single Print "RVI" (control for speed and current) which replaced 8 prints of the EGWL 13. In case you wonder what the other 5 remaining prints do: 3 THYM prints have thyristors on them than generate the field voltages for the main motor and generator. There is 3 of them because the generator has split field windings. The GR print is a basic rectifier (GR stands for Gleichrichter, German for rectifier), which generates the field voltages on inspection and recall operation. This is genius because it makes Insp on the Mic V with Transi M fully independent from any electronics. The Mic V itself could be dead but freeing trapped passengers is still possible without hand winding. Last but not least is the REU print, which is the analogue primary control of the voltage. All prints except the first mentioned RVI are the same as in Transi 2, just that all the extra prints Transi 2 had were combined into one. That is a short take on the Schindler DC systems, might at some point make an explanatory video on the topic. It's just that such a project takes a huge amount of time and effort, so I'll have to see when I might find the time to do so.

@ Wow, thanks for taking the time to write all of that. I would definitely watch an explainer video from you if you choose to make one. It might be worth putting all this info on a website or contributing to the elevator wiki.

Indeed, there is no inverter noise here and the motors are very silent. The constantly running MG sets are pretty loud though.

@TheLiftDragon ... but can be put in a soundproof room or box

@@pandabaerhellas That is true, sometimes the MG sets are located in a separate room. But here they aren't.

Yep, MRLs do be pretty fast and pretty tall nowadays.

Dankesehr!

Danke dir! Nun hier war Reservation ohnehin ein Gebäudezylinder. :P

SX is really cool indeed but they're also becoming more and more rare.

I can only record at 30 or 60 fps. Anyways, a change of framerate would not solve this problem as these displays run on 24VDC coming from a switching power supply. Their flickering/scrolling is independent from the 50Hz grid frequency.

@@TheLiftDragon Interesting. I always have problems with the frequencies of LEDs flickering colliding and causing that horrible effect on my camera. Usually recording at 50fps with 1/50th exposure is enough

@@mushroomcraft I know, that is a common problem with LEDs that have chap power supplies and run directly off mains voltage. But for lifts (as well as more complex LED setups) where the voltage is properly rectified first, this does not apply, at least not so easily. I have seen this flickering happen on different car position indicators in different speeds. I assume it has to do with the PWM frequency of the brightness control but still it's hard to fully figure.

@@TheLiftDragon it's always the PWM, along with being made worse by the rolling shutter. In the UK, the council estates have these energy saving LED lights in the corridors that all cameras hate. When the brightness changes because you triggered the PIR, it looks horrible on any camera. Manufacturers can't be bothered to use a higher PWM frequency, because most humans can't tell, but sometimes I can see the flickering with my own eyes, and it's so irritating. We live in a world where everything is getting cheaper, and we have to just deal with it.

Werde schauen, ob ich mal dazu komme, es ist ja keine Eile geboten. Habe aktuell noch viele andere Anlagen, auf denen mein Fokus zum Dokumentieren liegt. Einige grössere und schnellere Sachen.

Indeed, list installs in Switzerland are kept very clean. The pits surely are really clean now as these lifts have been fully replaced a few years ago, the footage is from 2020.

Would also have loved to see that but sadly the original equipment is long gone already. I have other videos in my backlog though that show original Schindler relay equipment - and quite some on my channel already.

Indeed these old DC motors have huge amounts of copper in them compare to more modern machines. I've also been to many derelict buildings and I've seen the work of copper thieves there... nothing nice at all. Though I am more than certain enough that nobody is just going to steal anything from these machines as they're in a rather secure and also very busy building. Such huge and fast lifts are not found in regular blocks after all.

Not that I know of. From the early 2000s on, Varidoor was used for Eurolifts and later on all was just Sematic. QKS was only installed in Schindler 500 and 700 models and now for new installs it's 7000 models only.

Indeed the Loher Dynalift sounds truly epic! I have some more of this and similar drives in my backlog, will upload them over time.

Hahaha, it does indeed. Nidec Unidrive always produces the funniest sounds.

Entweder man weiss genau, was man tut, oder man fasst an einer Steuerung generell nichts an.

@ ich würde erstmal lernen wie du und dann könnte ich das gleiche tuhen Die NewLift Steuerung ist einfach man kann alles machen bsw. Am pc den Aufzug eine Runde hoch und runter fahren zu lassen

@ aber erstmal ich darf das nicht aber ich wünschte ich dürfte das einmal bedienen
